I have implemented the following:

            ' If this is the default
            If nTimeout = 0 Then

                ' Wait for the process to complete before proceeding
                loProcess.WaitForExit()

                ' Do some code

            Else

                ' Wait for the process to complete before proceeding
                ' If the timeout occured before it finishes, lTimeout will be True
                If loProcess.WaitForExit(nTimeout * 1000) Then

                ' Do some code

                Else
                    lTimeout = True
                    loProcess.CancelOutputRead()
                    loProcess.CancelErrorRead()
                    loProcess.Kill()
                End If

            End If

The process works. If I pass a timeout value, it will go in the Else with a WaitForExit() with a timeout. If the processes finishes ok, all is ok. If the process finishes due to the timeout, it will go in the Else and will kill the application. At least, this is what it should do. But, the application remains in memory. loProcess.Kill() should terminate the EXE in memory. But, it does not.

Anyone would have an idea on how to fine tune this so it would work?
